摘要
Metal oxide-containing waste material is dried and preheated before being fed into a reactor (3) where it is melted and oxidised to produce a slag and a metal bath. The slag is then subjected to a two stage redn. pressure as it flows into an iron bath reactor (4) and then an iron bath calcinator (10). In the reactor, scrap or CO/CO2 is fed in to reduce mainly non-ferrous metals which form a bath which is subjected to segregation melting technique. A raw bronze melt is removed from the bottom of the vessel and recycled to the first reactor. In the second redn. stage, CaCO3, CaO and C and optionally O2 is fed into the vessel to reduce the FeO in the slag ad produce a pig iron melt.
